Mostly efficient with concrete commands and templates, but includes exposition Claude could infer (the 'Unlike posters... slides tell a temporal story' narrative, long rationale tables, and full placeholder-prose templates for the talk script and Q&A) that could be tightened. Not a 3 because of this padded narrative and template prose; not a 1 because the bulk is concrete, executable guidance rather than concept explanation.

Provides fully executable guidance: concrete bash checks ('which pdflatex', 'ls $PAPER_DIR/sections/*.tex'), a complete beamer LaTeX template, a python-pptx generation script outline, and an explicit state JSON schema. Not a 2 because the code is complete and copy-paste ready rather than pseudocode.

An explicit 8-phase sequence (0-8) with state persistence after each phase, a STOP checkpoint in Phase 1, and a Phase 4 validation loop (parse error → fix → recompile, max 3 attempts, pdfinfo page-count verification) plus AUTO_PROCEED=false enforcing confirmation. Not a 2 because validation checkpoints and feedback loops are explicit, not merely implied.

No bundle files exist (references/, scripts/, assets/ absent), yet the ~600-line body keeps large inline templates (full LaTeX template, talk script, Q&A) that could be split into reference files, and references an external helper (tools/extract_paper_style.py) and shared-references/integration-contract.md not present in the bundle. Not a 3 because content that should be separate is inline and referenced paths are unverifiable; not a 1 because sections are well-organized and references are at most one level deep.

Lists multiple concrete actions: 'Generate conference presentation slides', 'beamer LaTeX → PDF + editable PPTX', 'with speaker notes and full talk script', matching the anchor for listing multiple specific concrete actions. It is not a 2 because it goes beyond naming a domain and partial actions to enumerating several distinct deliverables.

Explicitly answers both 'what' (generate slides/PPTX/notes/script from a compiled paper) and 'when' via an explicit 'Use when user says...' trigger clause. Not a 2 because the trigger guidance is explicit rather than only implied.

Provides broad natural-term coverage in two languages ('make slides', 'conference talk', 'presentation slides', '做PPT', '做幻灯片', '生成slides', '写演讲稿', 'beamer slides for a conference talk') a user would actually say. Not a 2 because it covers many common variations rather than just a few.

Targets a clear niche (conference talk slides from a paper) with distinct triggers unlikely to fire for unrelated skills. Not a 2 because the scope is specific enough to avoid overlapping with general document or poster skills.
